Abstract

The present invention relates to a venting device for a sealed container, and more particularly to a safety venting device for a Lithium cell. The venting device is located on one of the two ends of a sealed container. The vent is comprised of a circular member which is recessed in the container end whereby it is concave with respect to the exterior of the container. Extending between the circular member and the container end are scored lines of weakness. As pressure increases in the container, the circular member deflects so as to develop stresses which become concentrated on the scored lines causing them to rupture at a predetermined pressure.
